This will work (thanks).... Tell me, is there a way to cross-reference the file handle to the variable I am using? Suppose I have something like open(IN, "< $myFile) Can I do some kind of system call to see what variable name is associated with 'IN'? Alternatively, I guess, I could do something like open(IN, "< $myFile) && ($myFileNum = fileno(IN)) or die "open failed" Thoughts?? -Jeff > Jeff Westman wrote: > > Isn't there a perl function to test if a file is already open?
